Respiratory device comprising a fastening system

Abstract

Disclosed is a device for respiration which comprises at least of one body that delimits an inner chamber from an outer chamber, a region for sealing the device against parts of the face of a patient, fastening elements for positioning the device on the patient's head and a connection for supplying respiratory gas. The device is equipped with an actuator, which when adjusted, changes the distance of at least one part of the device from at least one part of the body of the patient.

What is claimed is: 
     
       1. A breathing device, wherein the breathing device comprises a mask body which delimits an internal space from an external area; an area for sealing the breathing device relative to facial areas of a patient; fastening elements for positioning the breathing device to a head of the patient; a connection for supply of breathing gas; a forehead rest for supporting the breathing device at the head of the patient, comprising a forehead rest arm, a forehead rest support and a forehead rest shaft; and an adjusting member which, when being adjusted, changes a distance between the forehead rest and the head of the patient; wherein, in use, the distance between the forehead rest and the head of the patient is changed by a linear horizontal stepless adjustment of the forehead rest relative to the head of the patient, which adjustment is made possible by a connection in which the forehead rest arm is horizontally guided in a receiving element of the forehead rest shaft; wherein the forehead rest shaft is connected to the mask body and comprises at its upper end a receiving element which comprises a receiving opening for receiving the forehead rest arm, which receiving opening receives the forehead rest arm on a side adapted to face the patient and a tension lever on its opposite side; and wherein at least one of:
 the receiving opening comprises on the side adapted to face the patient a stop behind which resilient elements of the forehead rest arm having hooks at their ends grab and prevent the forehead rest arm from slipping out; 
 a cylindrical axis of the tension lever has a thickened portion at an end thereof; 
 the tension lever can be turned by 90° toward a right or left side. 
 
     
     
       2. The breathing device of  claim 1 , wherein the receiving opening has the form of a cylinder. 
     
     
       3. The breathing device of  claim 1 , wherein the receiving opening comprises inwardly located guide grooves which are complementary to the forehead rest arm and an axis of the tension lever. 
     
     
       4. The breathing device of  claim 3 , wherein the receiving opening comprises on the side adapted to face the patient a stop behind which resilient elements of the forehead rest arm having hooks at their ends grab and prevent the forehead rest arm from slipping out. 
     
     
       5. The breathing device of  claim 1 , wherein the receiving opening comprises on the side adapted to face the patient a stop behind which resilient elements of the forehead rest arm having hooks at their ends grab and prevent the forehead rest arm from slipping out. 
     
     
       6. The breathing device of  claim 1 , wherein the forehead rest arm is clamped in an adjusted position by rotating the tension lever into a fixed position. 
     
     
       7. The breathing device of  claim 1 , wherein a cylindrical axis of the tension lever has a thickened portion at an end thereof. 
     
     
       8. The breathing device of  claim 1 , wherein the tension lever can be turned by 90° toward a right or left side. 
     
     
       9. The breathing device of  claim 1 , wherein the breathing device further comprises an optical and/or tactile marking of an adjusted position of the forehead rest or the adjusting member. 
     
     
       10. A breathing device, wherein the breathing device comprises a mask body which delimits an internal space from an external area; an area for sealing the breathing device relative to facial areas of a patient; fastening elements for positioning the breathing device to a head of the patient; a connection for supply of breathing gas; a forehead rest for supporting the breathing device at the head of the patient, comprising a forehead rest arm, a forehead rest support and a forehead rest shaft; and an adjusting member which, when being adjusted, changes a distance between the forehead rest and the head of the patient; and wherein the forehead rest shaft comprises a tension device which clamps the forehead rest arm in the forehead rest shaft in an adjusted position, the tension device being present in a portion of the forehead rest shaft which is located below an opening in the forehead rest shaft which receives the forehead rest arm. 
     
     
       11. The breathing device of  claim 10 , wherein the portion of the forehead rest shaft which comprises the tension device is open on a side which is adapted to face the patient. 
     
     
       12. The breathing device of  claim 10 , wherein the forehead rest arm is clamped by a tension device in the form of a tension lever which is stored rotatably in the lower portion of the forehead rest shaft. 
     
     
       13. The breathing device of  claim 12 , wherein the forehead rest arm is clamped by a resilient element which presses from an inside against a lower end of the tension lever. 
     
     
       14. The breathing device of  claim 10 , wherein the breathing device further comprises an optical and/or tactile marking of an adjusted position of the forehead rest or the adjusting member. 
     
     
       15. A breathing device, wherein the breathing device comprises a mask body which delimits an internal space from an external area; an area for sealing the breathing device relative to facial areas of a patient; fastening elements for positioning the breathing device to a head of the patient; a connection for supply of breathing gas; a forehead rest for supporting the breathing device at the head of the patient, comprising a forehead rest arm, a forehead rest support and a forehead rest shaft; and an adjusting member which, when being adjusted, changes a distance between the forehead rest and the head of the patient; wherein, in use, the distance between the forehead rest and the head of the patient is changed by a linear horizontal stepless adjustment of the forehead rest relative to the head of the patient, which adjustment is made possible by a connection in which the forehead rest arm is horizontally guided in a receiving element of the forehead rest shaft; and wherein the forehead rest arm comprises resilient elements having hooks at their ends and the forehead rest arm has an approximately X-shaped contour and the resilient elements are located laterally in the X-shaped contour. 
     
     
       16. The breathing device of  claim 15 , wherein the breathing device further comprises an optical and/or tactile marking of an adjusted position of the forehead rest or the adjusting member.
